Evaluation of the Relationship between Friction, Texture, and Noise Properties of Preservation Treatments

This research project used texture, friction, and noise data collected along a number of asphalt pavements with different surface types across Texas to explore the intercorrelation between the three measures, both within each surface type and across different types. The research team found that across all surface types, the entire frequency band of noise from 400 to 5000 Hz correlates the strongest with texture of wavelengths from 31.5 to 2.5 mm positively, indicating that regardless of the surface type, pavements with a higher texture level in the wavelength spectrum of 31.5 mm to 2.5 mm tend to generate a higher level of noise. When each one-third octave band frequency noise is analyzed individually, the strongest positive correlation is found between noise of 630 Hz and texture of 50 mm wavelength. A negative correlation, however, is found between higher frequency (f > 1000 Hz) noise and shorter wavelength (ƛ < 10 mm) texture. The slope of noise versus texture is similar across different pavements, but the intercept can be different, indicating that with a unit increase in texture level, the additional noise generated by different pavements is of similar magnitude, but they might be at different levels of loudness given the same texture level. Across all pavement types, when texture level is the same, pavements with a thin overlay mix (TOM) surface tend to generate a consistently lower level of noise at both high and low frequencies. While no strong correlation was found between noise and friction, this finding is consistent with the conclusions from studies by many previous researchers.
